Béla Bartók’s “44 Duos” for violins are a set of marvelous musical miniatures that draw on the composer’s love of Eastern European folk music. Ranging from easy to advanced standard, they have long been the province only of string players with arrangements first for cellos and more latterly for violas. Now they are available to delight flautists and will be ideal for recitals, either as a main program item or as encores, just as violinists have enjoyed them since their composition.
